34 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Three plates were carried at each temperature, and measure- 
ments of the growth of the colonies of the mycelium were made 
each day for ten days, after which time the experiment was dis- 
continued because of the contamination of some of the plates 
and the drying out of others. The results are given in ta- 
e II.

If the growth of Fusarium conglutinans be compared with 
that of some of our more common saprophytic forms as, for 
example, Penicillium glaucum, or Aspergillus niger, as re- 
ported in the literature, it will be noted that, while the op- 
timum of these forms is also high, they can grow better than 
Е. conglutinans at the lower temperatures. In other respects 
the eurves of growth of these forms would approximate one- 
another very closely.
